Abstract: This study aims to produce an andragogy-based English module that is valid, practical and has a potential effect on student learning outcomes in semester 2 of Muhammadiyah University of Palembang. The research procedure used the Rowntree model, namely: planning, development, and evaluation. In the evaluation stage, Tessmer's formative evaluation model is used which consists of 5 stages, namely: self evaluation, expert review, one-to-one evaluation, small group evaluation, and field test. The result of this research is an andragogy-based English module. Modules are declared valid after being validated by material, language, and module design experts. The results of the one-to-one evaluation of 3 students stated that the students who were the research subjects gave very good responses to the andragogy-based module. The module is declared practical based on the results of one-to-one evaluations and small group evaluations. The results of the small group evaluation of 8 students obtained an average value of student responses to all aspects assessed at 82.47 in the practical category. The module is stated to have a potential effect on student learning outcomes because at the field test stage for 31 students, an N-gain of 0.58 was obtained, including the moderate category. Suggestions for lecturers, students and universities that this andragogy-based module can be used in learning English as well as for other researchers this andragogy-based module can be used as a reference in developing similar research.
